If you're regularly sent TinyURLs but have been burned one too many times by clicking through to an embarrassing link at the wrong time, head to TinyURL's preview page and enable previews. This old but useful feature will set a cookie in your browser, and henceforth all TinyURLs you click on with direct you to a landing page that will display the full link so you can make a more educated decision as to whether or not you should wait to visit the link. For similar solutions that change or preview TinyURL links on-the-fly, check out previously mentioned Embiggen bookmarklet or Tin Foil Hat.
